Thank you Briggs, can you provide a clear link between the forces acting in a simple gear system? Dr D says that the two forces are third law pairs, which I had originally taken to be the case when I asked the question and although that website says incorrectly "resisting force or inertia" it...

http://www.engineeringexpert.net/Engineering-Expert-Witness-Blog/tag/spur-gear This site talks about opposing forces f1 and f2 and says " To get a stationary locomotive to move, mechanical energy must be transmitted from the driving gear that’s attached to its traction motor, then on to the...

If not how does the force that is labelled in the diagram on the input cause the rotation that is shown on the input?

Thanks, so if I am rotating cog A must I apply a larger force to cog A than the reaction force from cog B in order to accelerate the system from a stationary position?

Hi all In respect to a simple gear system, two cogs are linked together, Cog A and Cog B. You apply a force to cog A, and cog A transmits this force to cog B through contact of the teeth on each cog (third law pair?) If cog A pushes on cog B, does cog B not push back on cog A? Does this not...

Consider the internal energy of a gas and solid (different materials) both at the same temperature, which material has the larger potential energy and why? Do they also both have the same kinetic energy? Finally is the definition of temperature as the average kinetic energy of the particles only...
